/**
 * RuntimeParameterAnnotationsGenericMethodTest is a test which check that
 * RuntimeVisibleParameterAnnotationsAttribute and
 * RuntimeInvisibleParameterAnnotationsAttribute are generated for both
 * generic and appropriate bridge methods.
 * All possible combinations of retention policies are tested.
 *
 * The test generates class which looks as follows:
 *
 * public class Test extends java.util.ArrayList<Integer> {
 *
 *     public boolean add(here some annotations java.lang.Integer) {
 *         return false;
 *     }
 * }
 *
 * Thereafter, various of combinations of annotations are applied
 * to the add, the source is compiled and the generated byte code is checked.
 *
 * See README.txt for more information.
